Swim with whale sharks and contribute

Each year, from September to December, we offer opportunities to join us and collect data on whale sharks.

Onboard partner operator Baleines Rand’eau, you will join tourists at sea and collect data (photo-ID, sex, size, scars, behaviour) using a tablet while working as a pair with another volunteer. You will then enter your collected data in our database, and directly visualise your contribution through close supervision with our field team.We provide a three-day training session (freediving, data collection on whale sharks at sea, data entry) to equip you with all the required skills necessary to contribute to data collection on whale sharks for the rest of your stay.

We are now fully booked for 2023, we will advertise the 2024 spots early next year!


No need to be a marine biologist. But make sure you check our requirements below before you apply 🤗 Please note this a multistep process with an initial questionnaire, screening process and interview.

I was lucky enough to participate 2 years in a row, 2 weeks each time, in the whale shark census campaign for the Madagascar Whale Shark Project, led by Stella Diamant. I enjoyed everything about this wonderful experience! When you see this magnificent fish, so impressive and so majestic at the same time, whether it is the first or the hundredth, the same emotion overwhelms you! It is a crazy experience! Humanly speaking, I also had the chance to meet incredible people, invested, warm, generous ... in short, I can't wait to go back very soon!
I was lucky enough to take part in the photo identification mission of the Madagascar Whale Shark Project. Apart from the human encounters, swimming with these giants of the sea remains a marvel. Moments filled with emotions, when we have the chance to observe the whale sharks in feeding position, when there are several of them or even when they come to the boat. If I had to do it again? .... Where do I sign?
Meeting a whale shark for the first time is incredible. To have the chance to experience this almost every day for the duration of the volunteer stay, surrounded by a team as friendly as they are professional, in an absolutely idyllic setting, is unforgettable ❤
